The _______________ ________________ problem is where vaccines must be kept at a certain temperature to avoid making them useless or ineffective.

Answers

The cold chain problem is where vaccines must be kept at a certain temperature to avoid making them useless or ineffective.

The delivery of vaccines to every part of the globe is a challenging task. To store, manage, and transport these life-saving goods requires a series of meticulously timed actions in temperature-controlled settings. We refer to this as a cold chain. The technique for moving and keeping vaccinations at temperatures between 35°F (2°C) and 45°F (8°C) is known as the "Cold Chain."Until the time of immunization, vaccines must be kept continually in a specific temperature range from the time they are created. This is due to the possibility of the vaccination losing its effectiveness if temperatures are too high or low (its ability to protect against disease). A vaccine's potency cannot be recovered or restored after it has been lost.
